Hi, what would be the most sutable type of thermocouple wire to be used for measuring a temperature around -5c to +5c ? I was planning to use the HH-25U or HH12C readout. Is Type T is more accurate than K or J for example?.

Thank you for your inquiry. At low temperatures, Type T is the most accurate of all thermocouple types.

Hi I am looking at purchasing a spool of TT-K-24-500 and I need it calibrated How do I go about doing this?

Hello, If you need the wire with a calibration certificate you can order as part number TT-K-24-500-CAL-3.

Hi, Is the wire compatible with organic/week acidic solution of chemical reaction to measure the temperature of the solution?

Hi Pawan, The thermocouple alloys may contaminate your process. For this I would recommend HSTC series; hermetically sealed in PFA thermocouples. https://www.omega.com/en-us/temperature-measurement/temperature-wire-sensors/hstc/p/HSTC-TT-20S-65 Best regards, OMEGA

What's the minimum bend radius?

Thank you for the inquiry. Please allow for 5 to 7 diameters of the wire (narrow side dimension). Best regards OMEGA

Hi, Is compatible with OM-CP-OCTTEMP-A? Regards

Hi, thank you for your question. OM-CP-OCTTEMP-A if definitely compatible with type K thermocouples. If you are making your own thermocouples with this wire, please remember to use miniature connectors (like SMPW-K-M) to plug directly into your logger.
